Forsythe is a solid swing tackle. JS just needs to invest in starters who can stay healthy and/or don't have chronic knee issues.
I was always taught if you do not understand something, break it down. Just for clartiy...
Solid? If referring to his physical state, he is mostly liquid contained in a membrane. So I think that suffices to say he is solid.
Swing? If referring to his function, like that of a gate, then it is about spot on. Simply trigger his latch and he swings open allowing you to pass.
Tackle? If referring to the potential result on our QB when he plays, this makes sense.
So what I hear you say is Forsythe is like a water balloon serving as a gate on the o-line which is causing his inabiliy to protect the QB. If so, I hear 'ya man.
If you are referring to his skills as being solid, I will ardently but respectfully disagree based on his performance in PS and yesterday. Maybe he has a deep understanding of both tackle positions...but he still needs to perform or that is about worthless.
